Title: Traveling transmission for working vehicle
Inventor: OTA YOSHIMI
IPC: F16H61/4069
Filed: 1998-06-09
Abstract: PROBLEM TO BE SOLVED: To restrict the shock at the time of starting a machine body and a jerk at the time of stopping the machine body by providing an orifice in an input oil passage of a neutral valve of a hydrostatic continuously variable transmission. SOLUTION: An orifice 25 is provided in each input oil passage of a forward moving neutral valve 20 and a reverse moving neutral valve 21. In the condition that the neutral valves 20, 21 are opened, as the discharged variable of a pump 11 is increased in a forward moving oil passage 13 of a motor 12 driving oil passage, a car body starts to move. Since the oil quantity flowing into the neutral valve 20 is restricted by the resistance of the orifice 25, sudden operation of a valve element in a valve closing direction is restricted. The neutral valve 20 is perfectly closed after the pressure in the forward moving driving oil passage 13 is raised, and a start can be performed without generating a shock.  In the case of operating the deceleration from some traveling speed change condition to the neutral position, the neutral valve 20 is operated in the passage opening direction, but the orifice 25 provided in the input oil passage of the neutral valve 20 resists so as to slow the passage opening operation, and the car body is stopped without generating a jerk.

Title: Printer
Inventor: IIZUKA SHINICHI
IPC: B41J19/68
Filed: 1991-07-02
Abstract: PURPOSE:To shorten printing time by returning a printing head to the left end of the same head position as a head position of a line where data is printed, if a line which is currently in the printing process or moving back the printing head to a position for starting the printing process of a following line immediately if information on such a position is available. CONSTITUTION:If the printing of a line which is currently in the printing process is completed, a carrier is moved back to the left end of a following line immediately in step 11, and the reception of printing data for the following line where data is to be printed is confirmed in step 12. If the head position of the following line is different from the left end, the difference is adjusted in step 13 and data is printed on that line in step 14. Thus the backward movement of the carrier is performed regardless of sent data and the printing position is adjusted only when the position of data for the following line to be printed is different from a position where the carrier returns. Thus the adjustment can be minimized and therefore, printing speed is accelerated when a text or an image where data is printed from the left end or the same position as a preceding line is intended for printing.

IPC: H01L21/316
Filed: 1979-12-14
Abstract: PURPOSE:To improve the hygroscopic problem of a PSG film by covering at least the front and the side surfaces of the PSG film with an Si3N4 film. CONSTITUTION:The PSG containing approx. 20mol% of P is used for the reduction of the surface stepwise unevenness or as a P diffusion source. The PSG film is exposed at connecting holes, scribe grooves and junction pad parts, absorbs water content and accordingly produces phosphoric acid, consequently erodes an aluminum wire, and finally disconnects it. Since the Si3N4 film incorporates high anti-hygroscopic property, when a semiconductor is covered with the Si3N4 film at leasto n the front and the side surfaces thereof thereby preventing direct contact with the atmospheric air, the semiconductor device can be covered with a protective film having high reliability.
